PI6C4512WE Equivalent & Substitute Parts

Part Overview

The PI6C4512WE is a PLL Clock Multiplier IC manufactured by Diodes Incorporated, designed for clock generation and timing applications with a maximum frequency of 200MHz. The device features a 1:2 input-to-output ratio with integrated divider and multiplier functionality, operating across a 3V to 5.5V supply range in an 8-SOIC surface mount package.

This part is classified as Obsolete. Substitute parts are necessary to maintain design continuity and ensure long-term component availability for new production runs and legacy system support.

Substitute Part Grouping Explanation

Substitution eligibility for the PI6C4512WE is determined by the following critical parameters:

Package compatibility: 8-SOIC (0.154", 3.90mm Width) form factor
Supply voltage range: 3V ~ 5.5V
PLL functionality with integrated divider and multiplier
Surface mount technology
RoHS3 compliance and REACH unaffected status
Maximum frequency capability: minimum 190MHz

The substitute parts listed below meet these core electrical and mechanical requirements. Packaging variants (Tube, Cut Tape & Digi-Reel®, Tape & Reel) represent different distribution formats of the same electrical device and are interchangeable at the component level.

Engineering Selection Recommendations

For applications requiring direct functional replacement of the PI6C4512WE, the onsemi NB3N502DG and NB3N502DR2G are the primary candidates. Both devices maintain the 1:2 input-to-output ratio, integrated divider and multiplier functionality, and identical package geometry. The NB3N502DR2G is supplied in Tape & Reel format, while NB3N502DG is supplied in Tube format; both are electrically equivalent.

The onsemi parts offer extended operating temperature range (-40°C to 85°C) compared to the original specification (0°C to 70°C), providing additional thermal margin. Both parts carry Active product status, ensuring continued availability and manufacturing support. All substitute parts maintain ROHS3 compliance and REACH unaffected status.

The Renesas 502MLF and 502MLFT devices are functionally compatible alternatives with identical package and supply voltage specifications. These parts feature a 2:2 input-to-output ratio and lack integrated divider functionality, making them suitable only for applications where the input-to-output ratio difference is acceptable. Both Renesas parts are classified as Obsolete.

Frequently Asked Questions (FAQ)

Q: Can the PI6C4512WE be directly replaced with the NB3N502DG or NB3N502DR2G?

A: Yes. Both onsemi parts are direct functional equivalents. They share identical package geometry (8-SOIC), supply voltage range (3V ~ 5.5V), PLL architecture with integrated divider and multiplier, and 1:2 input-to-output ratio. The primary difference is extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and Active product status.

Q: What is the difference between NB3N502DG and NB3N502DR2G?

A: Both parts are electrically identical. The difference is packaging format: NB3N502DG is supplied in Tube packaging, while NB3N502DR2G is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly requirements.

Q: Are the Renesas 502MLF and 502MLFT suitable replacements?

A: These parts are compatible at the package and supply voltage level but differ in functional architecture. The Renesas devices feature a 2:2 input-to-output ratio and lack integrated divider functionality, whereas the PI6C4512WE provides 1:2 ratio with both divider and multiplier. Substitution is valid only if the application does not depend on the specific input-to-output ratio or divider capability.

Q: What is the significance of the maximum frequency difference (200MHz versus 190MHz)?

A: The PI6C4512WE operates at 200MHz maximum, while all substitute parts are rated to 190MHz. For applications operating below 190MHz, this difference is not significant. Applications requiring operation above 190MHz cannot use these substitutes.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status. All parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited).
